<p><font face="Helvetica, Arial, sans-serif">Hi Liz,</font></p>
<p><font face="Helvetica, Arial, sans-serif">you question caught my
attention, as I have questioned this myself very often. Shiny
apps generally use DataTables to display table data. The Shiny
gallery also has some examples of using DT to display tables:</font></p>
<ul>
<li><font face="Helvetica, Arial, sans-serif">Overview:
<a class="moz-txt-link-freetext" href="https://shiny.posit.co/r/gallery/">https://shiny.posit.co/r/gallery/</a></font></li>
<li><font face="Helvetica, Arial, sans-serif">Simple example:
<a class="moz-txt-link-freetext" href="https://shiny.posit.co/r/gallery/widgets/basic-datatable/">https://shiny.posit.co/r/gallery/widgets/basic-datatable/</a></font></li>
</ul>
<p><font face="Helvetica, Arial, sans-serif">Taking at look at the
generated HTML does not look bad at first, as DT uses th
elements for headers and td elements for the cells. For a table
to be accessible, it is usually recommended to use the scope
attribute to associate data cells with the headers, as for
example WebAIM recommends:
<a class="moz-txt-link-freetext" href="https://webaim.org/techniques/tables/data">https://webaim.org/techniques/tables/data</a></font></p>
<p><font face="Helvetica, Arial, sans-serif">The problem is, that DT
does not associate th elements with td, as the scope attribute
is completely missing in the examples.</font></p>
<p><font face="Helvetica, Arial, sans-serif">Generally speaking, the
whole issue of accessibility of Shiny apps is pretty unclear. To
my knowledge, there is very scarce information on this, e.g.
Jumping Rivers published three or four blog posts on the topic
of accessibility:
<a class="moz-txt-link-freetext" href="https://www.jumpingrivers.com/tags/accessibility/">https://www.jumpingrivers.com/tags/accessibility/</a></font></p>
<p><font face="Helvetica, Arial, sans-serif">I would be happy if
somebody else has more info to share on this issue.</font></p>
<p><font face="Helvetica, Arial, sans-serif">Best</font></p>

Hi all,
Does anyone have experience with text output like tables in Shiny apps? The interactive display would be really good for some of my reports but I don't want to spend time on it if I won't be able to navigate and read the output.
Liz
